This one's only Moderate in difficulty because her Face and hair are Exactly the same... There are subtle clues in the pic.
There's also a way to Cheat and get the answer... I'm not going to bother to fix the Cheat either, because it WON'T help with the Hard pics.
Inspector Penny and Brain Gadget....
Here's the story...
Inspector Gadget finally reaches Dr.Claw... Dr.Claw being a man of business and efficiency, takes note that the ONLY problems that he's EVER had has been with Inspector Gadget... so he offers him a settlement to let him go... Gadget refuses. That leaves claw only ONE choice.
Poor Gadget ALWAYS worked alone (So he thought)... Therefore no one was there to help him as Dr.Claw ordered his men to Kill him. Using a EM pulse gun, and a Bed saw on the Helpless Inspector. Penny and Brain watched in Horror as they Dismantled him piece by piece. Brain Rushed in to help and was Immediately shot.
The cops came in eventually, and rescued Penny, but it was too late for Gadget and Brain. Dr.Claw was long escaped as well.
That was years ago.
It didn't take long for Chief Quimby to Learn that Penny was in fact the mastermind behind Gadgets work. So he offered her a Job on the force. Feeling Responsible in a way for her uncle's Demise, she accepted to continue his work... Even augmenting herself with Her uncles patented Gadgets and Automation Surgeries (Up dated of course)...
Her computer book, converted into "2nd brain". Her Autodog companion.
She is well trained, Smart, Nimble, Ruthless against M.A.D.D., and has Nothing to lose.
Inspector Penny Gadget.
